There are a few interfaces that will go beyond the 32i/o limit, such as Focusrite's Rednet HD32R and Red 4Pre and 8Pre, the Apogge Symphony I/O, Lynx Aurora, and Waves Digigrid DLI and DLS. But they require an HDX or HD Native card to operate.

The 32 io limit is for every 3rd party system, it is not a vanilla/HD thing.

max 32 if you have 3rd party interface
max 64 if you have Avid HDN
more if you have Avid HDX

To be more precise: max 32 via ASIO. Unless you have a special iLok license key to unlock 64 ASIO I/O for the Pro Tools non-HD which comes with the S3L to record/soundcheck via AVB.

Word on the street (allegedly a comment by Avid staff at a trade fair) is that Avid licensed only 32 I/O with Steinberg (who owns ASIO). I guess they have to pay more for the 64 I/O to Steinberg. Then again, crippling ASIO I/O was certainly in their product management interest too.
